Sinks

Last updated Oct 1, 2026 Sinks define destinations for your data in Basin Pipelines. They support writing to Basin Catalog as Apache Iceberg tables or to R2 as raw JSON or Parquet files.

Sinks provide exactly-once delivery guarantees, ensuring events are never duplicated or dropped. They can be configured to write files frequently for low-latency ingestion or to write larger, less frequent files for better query performance.
